' This invention relates to a new and my proved form of oil and greaseapplicator, for polishing or buiiing'wheels.

Oneobject of the invention is to eliminate the throwing of oil'or greasewhen applying same to any moving surface.

()ther objects will be noted from the following description andaccompanying draw inns and in which: V

Figure 1 is a front view of theapplicator pivotally attached to a guardand in raised or rest position.

Fig. 2 is a similar view with the applicator in lowered or Contactposition,

Fig. 3 is a side View, enlarged, with the applicator partly in section.

F ig. l is a side elevation of the applicator, with the guard in sectionand the rest position and contact position both being shown.

Fig. 5 is an enlarged front elevation of the '12 and 13 and stop bar 14,is pivotally attached to a guard 15 mounted over a polishing wheel 16 ona shaft 17, said hanger pivots at 18 to allow the applicator to swingdownward to contact with thepolishing wheel 16, the stop bar 14 thenresting on the top surface of the guard 15. p

The applicator shell or casing 19, with l channel forming flange 20 andto the upper edge of which is attached a flexible bracket 21 with insetbrushes 22, is attached to the hanger by the cross bars .12 and 13mounted through sleeves 23 and 24: respectively, and

said sleeves may be mounted on the outer surface of the applicator shell19 by suitable means such as riveting. The brush wipes-the surface ofthe wheel 28.

Bolted to the applicator shell 19 is a handle 25 mounted slightly to therear of the sleeve 23, while just forward of the sleeve 24 is at tacheda container 26. thespout 27 beingattached in such. 1 i-anncr asto'forinafiXe d part of the applicator shell =19. The container 26 can filledwithoil orgreaseand -turned into the screw top of thespout 2?, thus "asthe hanger and applica or are drawiiforward and swung downward to thecontacting position the oil or grease feeds to the buffing Y or applyingwheel 28 which in turn lubricates the polishing wheel 16. r The buffingwheel 28 is mounted on a shaft 29, and at each end of said butting wheelthere the shaft 29 by a cotter 'pin- 32.- Hooked through the head of thecotter pin 32 is a spring 33 the other end of the springbeing anchoredto the lug 34 on the inside surface of the applicator shell 19. 1

The springs 33 hold the bufiing wheel 28 down against the spout 27 whenthe applica- .is a washer and link 31 held in position on tor is not inuse, but when the buffing wheel is in contact with the polishingwheelv16the lever arm 31 pivots on pins 34 mounted through the walls ofthe applicator shell 19 and thus carries the butting wheel 28 upwardwith the pressure.

. B ifer springs 36 are attached to the in her surface of the applicatorshell 19 to .pr vent the shifting of the buffer wheel 28.

This apparatus may be used as a hand applicator by removing the hangerand grasping the container and applying in-the manner that the presentgrease stick is used.

Inthe modification shown in Figs. 6 to 9 inclusive, a spraying device isusedin place of the container. The sprayer 40 has a fiat surface illwith a depression 12- havinga plurality of apertures 43 slightly to oneside of the middle of the said depression. The

applicator shell 19a and with the apertures 43 on the lower side.Between the sprayer and sprayer 40 is bolted to the inner surface of thethe applicator shell is a gasket of cork or the like, said gasket 44%partaking of the shape of the flat surface of the sprayer; bolts 45holds ing both sprayer 4:0 a nd gasketll in position over the aperture46 in the threaded'stem 47 which is an integral part of the applicatorshell 19a.

Screwed on the threaded stem 47, outside and its guard, of a lubricantapplicator pivotally mounted on the guard and comprising av oftheapplicator shell, is a screw connection 48 with a tapered tubular end 49to which a hose may be attached through which the oil or grease may befed by pressure, to the sprayer40 and thus through the apertures 43 tothe bufling wheel. The use is similar to that above described.

WVe claim: a

1. A lubricant applicator for polishing wheels comprising a shellpivotally mounted over the wheel, a lubricant bottle carried by theshell and arranged to be tilted therewithagainst the applying wheel.

3. The combination with a polishing wheel shell pivoted to the guardabove the wheel, an applying wheel mounted in the shell and movabletherewith into and out of contact witlr the polishing wheel, and meansto supply'lubricant to the applying wheel, said means including a nozzlefixed in the shell and an oil receptacle attached to the nozzle andarranged to swing with the shell to either upright or inclined position.

4. A lubricant applicator as in claim 1, the mounting for the applyingwheel including a pair of links pivoted to the shell, and springsbetween the links and the shell permitting yielding movement of theapplying wheel.
